Enhanced abrupt autofocusing and depth-of-focus of circular Airy derivative beams via controlled asymmetry
Anita Kumari, Vishwa Pal
We demonstrate simultaneous enhancement of abrupt autofocusing and depth-of-focus (DOF) in circular Airy derivative beams through controlled asymmetry. The controlled asymmetry ena…
Spatially multiplexed concentric discrete optical vortices: Complex topological structures and unconventional rotational dynamics
Aditya Narayana Jena, Vishwa Pal
The paper presents a discrete optical vortex platform using concentric rings of phase‑locked lasers to create shape‑invariant vortex beams whose intensity rotation can be reversed…
Influence of Refractive Index Distribution on Multimode Soliton Dynamics and Condensation in GRIN-MMFs
Love Kumar Sharma, Vishwa Pal
Optical solitons propagating through a multimode fiber represents one of the most fascinating class of objects exhibiting peculiar properties, with widespread potential for applica…
Generating non-diffracting bottle beams with a flat multi-level diffractive lens
Andra Naresh Kumar Reddy, Srinivasa Rao Allam, Ashish Tiwari +4
We introduce a novel method for creating a high-quality, sharply defined, non-diffracting optical bottle beam by focusing a Bessel beam propagating through a flat multi-level diffr…
